Communication with Bluetooth LE peripherals in the concept of the Internet of Things

This bachelor thesis deals with the design of a solution for communication between web applications and Bluetooth Low Energy devices using hybrid applications. The proposed solution is then demonstrated in praxis on an existing web application. At first, the reader is introduced to Bluetooth Low Energy technology and the concept of hybrid applications. The thesis then introduces an existing web application of authors own creation. The main use for the application is management of shared assets between its users. The main functions include, among other things, record keeping of location of these assets, however the location must be entered into the application manually. Based on this, a technological solution combining Bluetooth LE beacon and a hybrid application for the Android operating system is proposed. This solution would make it possible to fully automate the location record keeping of shared assets. The solution is subsequently implemented, so a hybrid application for the Android operating system and firmware for the tracking beacon will be created. Both the application and the firmware are then tested. Beacon testing meets all expectations. However, while testing the Android application, it comes to light, that some components of the chosen technology are obsolete and it would thus be appropriate to choose another technology, or in this particular case to abandon hybrid applications altogether. Despite this, the goals set for this thesis are met and the resulting application remains usable.
